(fo cir/ZZ whom it may concern:

Be it known that we, DARWIN HANAUER, a resident of Long Island City, inthe county of Queens, and THOMAS VEITCH, a resident of Yonkers, in thecounty of Westchester, State of New York, have jointly invented new anduseful Improvements in Speed-Controlling Mechanisms for Motor-Vehicles,of which the following is a specification.

This invention relates to interlocking mechanism particularly adaptedforcontrolling the gearin gs by which different speeds are transmittedfrom a driving to a driven shaft.

The improvements comprised in the invention are primarily designed foruse in motorvehicles where it is'desirable to change the speed of thevehicle independently of the speed of the motor. is obtained byemploying on the driving-shaft a plurality of gear-wheels revolved by.the shaft, but longitudinally movable thereon, so that they mayseverally be thrown into engagement with corresponding gear wheels fixedon a shaft driven thereby, providing different combinations by whichdiiferent speeds may be obtained. To control these sets ofvariable-speed gears and to secure the desired position of each set withrespect to the others by a simple operation are the leading purposes ofthe present invention.

The further purposes willfully appear from the following descriptionandthe accompanying drawings,relating to the improvements.

Referring to the drawings, Figure 1 is a plan View of mechanismembodying the in- Fig. 11L is a bottom View of the reverse mechanism.Fig. 1b is a front view of the mechanism shown in Fig. l, Fig. 2 is aview in sectional elevation taken on the line 2 2 of Fig. 1. Fig. 3 is afront view of mechanism embodying the improvements. Fig. 4 is a sideview of mechanism for securing the disengagement of the advancing gearswhen the reverse is engaged, and vice versa; and Fig. 5 is a rear viewof the mechanism illustrated in Fig. 4.A

As shown in the drawings, the frame 1 carries' a revoluble shaft 2,operated by the handwheel 2' and provided with a suitable support byfixing thereon a collar 3, yadapted to turn on the bearing 4, the shaft2, being This variation in speedhollow and sleeved on the shaft 5, isrevolved by the hand-wheel 5', for operating the steering-gear 6. Fixedto the shaft 2 is the primary segmental Wheel 7, having thegear-segments 3 9 and the blank segmentsl() 11, as also the catch 12 andthe segmental projections 13, with the openings 14 between them.

.Iourualed in the frame 1 are the secondary segmental wheels 15 and 16.The wheel 15 has the gear-segments 17 18 and the blank segments 19 20,adapted, respectively, to engage with the corresponding gear-segmentsand blank segments of the primary segmental wheel 7, and the wheel 16 isprovided with the gear-segments 2l 22 and the blank segments 23 24,which engage, respectively, with the corresponding gear-segments andblank segments of the primary segmental wheel 7.

Connected to the secondary wheel 15 by an eccentric pivot 25 is a rod26, having a pivotal connection 27 with well-known variablespeedmechanism comprising the longitudinally movable rod 28, having an arm29, which moves the gears 30 and 3l along the driving-shaft 32, so thatthe gear 30 may engage the gear 33 to produce the first speed or so thatthe gear 3l may engage the gear 34 to produce the third speed or so thatboth gears 30 and 3l may be held disengaged from the gears 33 and 34,and in like manner there is connected tothe secondary Wheel 16 by aneccentric pivot 35 a rod 36, having a pivotal connection 37 with furtherWell-known variable-speed mechanism comprising thelongitudinally-movable 4rod 38 with the arm 39. for moving the gears 40and 41 along the drivingshaft 32, so that the gear 40 may be broughtinto engagement with the gear 43 to produce the second speed or so thatthe gear 4l may be brought into engagement with the gear 44 to producethe fourth speed or so that both gears 40 and 41 may be held disengagedfrom the gears 43 and 44.

The primary segmental wheel 7 is normally held in fixed position by alock comprising a bolt 45, which reciprocates in bearings 46 and isadapted to enter the openings 14 between the projections 13. 47 isadapted to engage the openings 14,'and a pawl 48 is adapted to engagethe catch 12, both latch and pawl being fixed to the frame A springlatch or brake 1 and by their engagements with the primary wheel servingto control the same in operation, as hereinafter described.'

The foot-lever 49, fixed to a shaft 50, which is journaled in bearings5l, has an arm 52, having a pivotal connection 53 with the bolt 45, bywhich the latter is reciprocated. This foot-lever has the usual arm 54,connected with the crank 55, for disengaging the driving-shaft clutch 56from the motor. It will be seen that when the driving-clutch is engagedthe bolt connected therewith will lock the primary Wheel and themechanism controlled thereby.

The foot-lever 60 is loosely mounted on the l shaft 50 and is providedwith a lug or lugs 61, which engage with a stop or pin G2 of the shaft.with., and operates the usual brake-rod64, the operation of thefoot-lever and the brake connected therewith simultaneously operatingthe clutch. Hence when the brake-foot lever is depressed the clutch isfreed, as is also the primary wheel, and the brake is applied.

The reversing mechanism employs the usual lever 70, fulcrumed at 7l andheld bythe rack 72, the lever being pivoted to the rod 73, which effectsthe engagement ot' the gearwheels 74 with the gear-wheels 30 and 3l in awell-known manner for reversing-that is toisay, the rod 73 carries a pin73', which lies in :L slot 73 of the reciprocating cam 74", the cam`being connected with and adapted `to rockathe. crank-lever 74, whichcarries the reverse-gear 74, and hence thereciprocation i of :the rod 73throws the reverse-gear into and out of engagement. To eect theinterlocking of the reverse and the advance gearingA toithelever 70,there is connected by a pivot 75 a link.76, having a `pivotal connection77 with a lock comprising thearm 73 and a rocking latch 79, which ispivoted at the points SO to fixed bearings S1.` The latch 79 is providedwith the notches S2 and 83, with which the rods 26 and 36 must registerin order that the reversing-gear may be engaged, for the reversing-levercannot be thrown unless the latch is` permitted to rise by suchregistration, as otherwisethe rods hold the latch down. When the rods 26and 36 register withithe notches 82 and 83, by elevating the latch 79the projections 26 and 36' on the respective rods are engaged,v the rodsand the gears operated thereby thusbeing locked.

A dust-proof casing 85 incloses the segmentalwheels and their immediateconnections, the openings required for the operation of the movableparts, as the rod 36, being protected by a cover 86, movable inaguidesS7 asn required by the oscillations of the rod passing therethroughiInoperatiomwith the mechanism in the positioniillustrated in Fig. 1, thebolt 45, by engagement with an aperture between the projections 13,locks the primary segmental wheel 7, which in turn locks the secondarysegmental wheels 15 and 16 through the engagement Theifoot-lever arm 63is connected of the convex blank segment 10 with the respective concaveblank segments 20 and 23. The secondary wheels are thus locked in suchposition that they fix the advancing gears out of engagement, the samesliding on the rod 32, being revolubly held by the spline 32. 1Vlhcn theadvancing gears are out of engagement, as shown, the shifting-rods 26and 36 are held in position such as to permit the reverse-lever 70 tothrow the reverse-gear into engagement and the latch 79 to engage thestops 26 and 36', thus preventing any change of gearing while thereverse is engaged. When the reverse is disengaged, the advance gearingmay be engaged by depressing either foot-lever 49 or 60, therebywithdrawing the bolt 45, and then turning the shaft 2 and the primarysegmental wheel 7 operated thereby. If this Wheel be turned to the left,its gearsegmentS engages the gear-segment 17 of the secondary segmentalwheel 15,1vhich is thereby revolved until the gear-wheel 30 engages thegear-Wheel 33 for the first speed, the primary wheel being held at thedesired position by the rengagement of the bolt 45 with the primarywheel, which has been checked at the desired point by the brake 47engaging with the projections 13. This revolution of the primary wheelhas not moved the secondary wheel 16, since the blank segment 10 stillengages the blank segment 23, thus holding this secondary wheel and thevgearing connected therewith. If the primary Wheel be turned to the leftuntil it is checked by the engagement ot' the catch 12 with the pawl 48,the

blank segment 10 still continues to engage Fig. 1 if the wheel 7 beturned to the right; its gear-segment 9 engages the gear-segment 2 andturns the wheel 16, so that `it throws the gear-wheel 40y intoengagement with the gear-wheel 43 foriproducing the secondspeed. It therevolution of the wheel 7 be continued to the rightuntil its blanksegment 11 engages the blank segment 24, the second-speed gears 40 and43 are disengaged, while `the blank 10 still engages the blank 20- ofthe lwheel 15, thus holding` the first-speed gears disengaged when thesecond-speed gears are engaged. It after throwing the second-speed gearsout of engagement the revolution ofthe wheel 7 be continuedito theright, its gearsegment 9 engages the gear-segment13 ot" the wheel 15,thus throwing the gear-Wheel 3l into mesh with the gear-wheel 34, which'produces the third speed. By-continuing theirevolution ofthe wheel 7 tothe right` its blank 1l is broughtinto engagementwith the blank 19 ofthe wheel y15, and the third-speed gears are thus held disengaged whilethe blank l1 still engages the blank' 24 of the wheel `16. `Bycontinuing to the 'right the revolution of the wheel 7 its gear- IOO IIO

segment 8 is brought into mesh with the gearsegment 21 of the wheel 16,thus throwing the gear-wheel 41 into engagement with the gear-wheel 44,which produces the fourth speed, and by continuing the revolution to theright the gears for producing the fourth speed are disengaged and thegears for producing the first speed are brought into mesh.

From the foregoing description it will be seen that it is impossible tochange the speed without first releasing the driving clutch, that it isimpossible to change the speed when the reverseis in, that it ispossible to reverse only when all speeds are in free position, and toproduce by the reverse only the first speed. It will further appear thatthe consecutive increasing and decreasing speeds may be obtained andthat change may be made directly from the highest to the lowest, but notfrom the lowest to the highest. All parts are capable of assemblage incompact relation on a single plate or frame within the ready control ofthe operator.
